Godly Upgrading System: Full Level Instantly

At this moment, a voice sounded in Ye Ziheng's mind. The person who spoke was Blood-feathered Demon Sovereign.    

"He was taken care of by someone? Who took care of him?"    

Ye Ziheng asked with a confused expression.    

"I'm not sure. Anyway, I have never seen him before, but the Qi on his body is very familiar. It should be the same person who was attacked by you at the entrance of the Heavenly Star Sect. The other guy called him some Outsider. I'm not very familiar with him. "    

"Last time. Outsider?"    

After hearing what the Demon Sovereign said, Ye Ziheng immediately recalled what Black-robed Man looked like.    

However, what puzzled him was that Black-robed Man had been arguing with him the whole time. Why would he come and help him this time?    

"Oh, right. He seems to have left something for you in the coffin. Do you want to go and take a look?"    

Ye Ziheng was stunned when he heard that. He walked to the side of the coffin and looked down. At first glance, he saw the extremely familiar box lying quietly in the coffin.    

"It really is that guy."    

Ye Ziheng said. Just now, he was a little suspicious about whether the person the Demon Sovereign was talking about was Black-robed Man or not. But now, it seemed like he was right. After all, this box was his trademark item.    

After picking up the box, Ye Ziheng found that there seemed to be something similar to a button at the bottom of the box. However, Ye Ziheng didn't care about it. He wanted to see what was good in the box now.    

Then, the box was gently opened in Ye Ziheng's hand, but the expression on Ye Ziheng's face changed from excitement to disappointment.    

In the box, there were only three books that looked very ordinary. Other than that, there was nothing else.    

"Why are there so few things? Didn't you give dozens of Magical Treasures in the past?"    

As Ye Ziheng spoke, he took out the three scrolls of martial skills. Then, he carefully inspected the box again, but he still did not find anything else.    

"These three scrolls don't seem to be simple. I think it's better for you to open them and take a good look."    

The voice of the Demon Sovereign entered Ye Ziheng's mind. Ye Ziheng looked at the three scrolls in his hand and felt that it made sense.    

The things that guy gave him each time were very good. Unless he went bankrupt, it was impossible for him to give them away in such a shabby manner. There must be some big article in these three scrolls.    

Therefore, Ye Ziheng opened one of the books and started reading.    

After reading for a few seconds, Ye Ziheng's expression changed drastically.    

In the book, there was a blueprint of a human body, and beside it, there was a large paragraph of words.    

Ye Ziheng read it carefully for a while, and then he was so shocked by what was written in the book that he fell to his knees.    

"What do you think, kid? Is it something good?"    

The voice of the Demon Lord rang out in Ye Ziheng's mind with a hint of a smile.    

"This seems to be a book that introduces the cultivation matters of martial artists. The various matters that one needs to pay attention to when cultivating from Rank-1 to Rank-9 are recorded in it. This includes the cultivation of Extreme Physique, extreme bones, and so on. Every single one of them is written in great detail. "    

As Ye Ziheng spoke, his tone carried a trace of disbelief.    

"Is there a book name written on it?"    

The Demon Sovereign asked again.    

When Ye Ziheng heard that, he turned back to the front of the book and saw three big words written on it.    

"Mortal Martial Theory."
